Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
DuraFlex Chimney Cleaning in Rialto, CA | San Bernardino Chimney Sweep
We provide independent DuraFlex chimney cleaning and repair across Rialto, including both 92376 and 92377. We’re not manufacturer-affiliated or authorized by DuraFlex, but we’ve worked on their full liner and cap line in hundreds of Inland Empire homes. What makes our DuraFlex work different here is simple: Rialto sits at the mouth of the Cajon Pass, and that wind corridor fills flues with debris most chimney companies in neighboring cities never see. If your DuraFlex cap is clogged or your liner is pulling smoke back into the house, call (877) 516-7159.

Why Rialto Residents Choose Us for DuraFlex Service
Most companies that sweep chimneys in Rialto will clean whatever liner is in the flue. We go further because we actually know how DuraFlex systems behave under this city’s specific conditions. Allen Prescott, our owner, grew up near the Kendall Drive corridor in DuraFlex in San Bernardino and has spent close to three decades working on Inland Empire fireplaces. He’ll tell you directly what’s happening in your flue, what needs work now, and what can safely wait.
Our familiarity with DuraFlex’s full line means we don’t diagnose a symptom and hope. We look at the liner, the cap, the connection points, and the surrounding masonry as one system. For DuraFlex sales & service, we stock genuine replacement caps, dampers, and liner sections so repairs don’t stall waiting on parts.

Common DuraFlex Chimney Cleaning Problems We Solve in Rialto
- Wind-packed debris at the flue top. The Cajon Pass downdrafts push leaves, dust, and tumbleweed fragments straight into uncapped or poorly-screened DuraFlex flues. We pull this material out regularly on the 92376 flats, then check the cap screen for damage from impact.
- Creosote glazing in uninsulated single-wall liners. Rialto’s winter nights get cold enough for fires, and older tract-era homes often have 304 single-wall liners that were never sized correctly. The result is uneven flue temperatures, heavy creosote accumulation, and stage 3 glazing that becomes a real chimney-fire risk during Santa Ana conditions.
- Corrosion at the liner-to-cap connection. Seasonal moisture settles against older crowns, and when the crown cracks, water works its way down the liner connection. We see this on the original brick-and-mortar fireplaces throughout Rialto’s mid-century housing stock. A corroded connection means exhaust gases leak into the chase or wall cavity.
- Smoke rollback during wind events. DuraFlex caps can’t maintain draft when debris blocks the screen or the flue was sized wrong for the fireplace. Homeowners describe the living room filling with smoke every time the Santa Anas pick up. That’s not normal, and it’s rarely just a damper issue.
- Damper and firebox component failure in surrounds with spalled brick. When Rialto’s dry-heat summers and wetter winters cause masonry to flake and shift, the firebox no longer holds a tight seal for the DuraFlex liner. The result is airflow problems and, in some cases, visible soot around the fireplace opening.
DuraFlex Service in Rialto: What Local Conditions Mean for Your Equipment
Rialto’s position at the base of the San Gabriel and Cajon Pass wind corridor is the one factor that separates our DuraFlex work here from Fontana DuraFlex service or Colton. Those neighboring cities sit outside the direct wind path, so their flues accumulate creosote the standard way. Rialto flues accumulate creosote plus whatever the pass winds carry south. Our crews routinely pull wind-blown dust, leaves, and tumbleweed fragments out of DuraFlex caps and flues before a sweep even starts. On a recent job in the 92376 flats, a packed wad of tumbleweed and leaves had completely blocked a DuraFlex 304 single-wall liner cap, forcing smoke back into the living room every time the Santa Anas blew. After clearing the debris and replacing the damaged cap with a DuraFlex multi-flue model, the draft improved immediately and the downdraft smoke stopped. That’s the Rialto-specific pattern: your cap screen may be catching more than it was ever designed to handle. We check for that on every visit, not just during annual sweeps.
DuraFlex Models & Products We Service in Rialto
We work on the DuraFlex 304 Alloy Single-Wall Chimney Liner Kit, the 316Ti Alloy Insulated Chimney Liner Kit, the Pro Flexible Chimney Liner, and the Stainless Steel Rain Cap line. For parts, we use genuine DuraFlex replacement caps, dampers, and liner sections for exact-fit repairs. When OEM parts are discontinued or back-ordered, we use quality aftermarket components and tell you exactly what we’re installing and why. The approach is straightforward: if your liner is still sound, a targeted cap or damper repair beats a full replacement. If the liner is corroded and one season from failure, we won’t patch it and walk away.

FAQs – DuraFlex Chimney Cleaning in Rialto
Rialto’s position at the mouth of the Cajon Pass means wind-driven debris hits your cap harder and more often than it would in DuraFlex repair in Muscoy or Colton. We routinely pull leaves, dust, and tumbleweed fragments off DuraFlex caps in Rialto, particularly in the 92376 flats, and that debris blocks airflow and causes smoke rollback. Call (877) 516-7159 if your cap is clogged or your fire is burning dirty.
Yes. Rialto’s rental-heavy housing stock and deferred maintenance patterns mean many chimneys haven’t been inspected in a decade or more. A Level 2 inspection checks the liner’s internal condition, the cap, and the connection points. If you’re listing a Rialto home, you want this done before the buyer’s inspector raises it. Call (877) 516-7159 to schedule one.
Usually just the cap. Corrosion at the liner-to-cap connection, impact damage from wind-blown debris, and failed screens are all repairable without touching the liner itself. We’ll only recommend liner replacement if the liner itself is corroded, cracked, or unsafe. Call (877) 516-7159 for an assessment.
Install a properly-fitted cap with an intact screen, and clear the screen whenever you notice debris collecting. Rialto’s pass winds are relentless, so we also check the cap and flue top during the annual sweep rather than assuming it’s fine. If you’ve been cleaning the screen yourself and still getting rollback, call (877) 516-7159 – there may be a deeper blockage inside the flue.
We service both. Rialto’s mid-century tract homes include many gas inserts, often retrofitted behind older masonry fireplaces. DuraFlex liners on gas inserts need different inspection points than wood-burning systems, particularly around the termination cap and air intake. Call (877) 516-7159 and we’ll tell you what your unit needs.
